+| ... | Rate) with zero packet loss tolerance or throughput PDR (Partial Drop\
+| ... | Rate) with non-zero packet loss tolerance (LT) expressed in percentage\
+| ... | of packets transmitted. NDR and PDR are discovered for different\

+| ... | algorithms with configured starting rate and final step that determines\
+| ... | throughput measurement resolution. Test packets are generated by TG on\
+| ... | links to DUTs. TG traffic profile contains two L3 flow-groups\
+| ... | (flow-group per direction, 50k flows per flow-group) with all packets\
+| ... | containing Ethernet header, IPv4 header with IP protocol=61 and static\
+| ... | payload. MAC addresses ranges are incremented as follows:

+| ... | *[Ver] TG verification:* TG finds and reports throughput NDR (Non Drop\
+| ... | Rate) with zero packet loss tolerance or throughput PDR (Partial Drop\
+| ... | Rate) with non-zero packet loss tolerance (LT) expressed in percentage\
+| ... | of packets transmitted. NDR and PDR are discovered for different\
+| ... | Ethernet L2 frame sizes using either binary search or linear search\
+| ... | algorithms with configured starting rate and final step that determines\
+| ... | throughput measurement resolution. Test packets are generated by TG on\
+| ... | links to DUTs. TG traffic profile contains two L3 flow-groups\
+| ... | (flow-group per direction, 5k flows per flow-group) with all packets\
+| ... | containing Ethernet header, IPv4 header with IP protocol=61 and static\
+| ... | payload. MAC addresses ranges are incremented as follows:

+| ... | Rate) with non-zero packet loss tolerance (LT) expressed in percentage\
+| ... | of packets transmitted. NDR and PDR are discovered for different\

+| ... | algorithms with configured starting rate and final step that determines\
+| ... | throughput measurement resolution. Test packets are generated by TG on\
+| ... | links to DUTs. TG traffic profile contains two L3 flow-groups\
+| ... | (flow-group per direction, 500k flows per flow-group) with all packets\
+| ... | containing Ethernet header, IPv4 header with IP protocol=61 and static\
+| ... | payload. MAC addresses ranges are incremented as follows:

+| ... | 802.1q tagging is applied on link between DUT1 and DUT2.
+| ... | *[Cfg] DUT configuration:* DUT1 and DUT2 are configured with L2 bridge-\
+| ... | domain and MAC learning enabled. Qemu Guest is connected to VPP via\
+| ... | vhost-user interfaces. Guest is running DPDK testpmd interconnecting\
+| ... | vhost-user interfaces using 5 cores pinned to cpus 5-9 and 2048M\
+| ... | memory. Testpmd is using socket-mem=1024M (512x2M hugepages), 5 cores\
+| ... | (1 main core and 4 cores dedicated for io), forwarding mode is set to\
+| ... | io, rxd/txd=1024, burst=64. Scheduler policy is set to SCHED_RR with\
+| ... | priority 1 for all Qemu CPUs. DUT1, DUT2 are tested with 2p10GE NIC\
+| ... | X520 Niantic by Intel..
+| ... | *[Ver] TG verification:* TG finds and reports throughput NDR (Non Drop\
+| ... | Rate) with zero packet loss tolerance or throughput PDR (Partial Drop\
+| ... | Rate) with non-zero packet loss tolerance (LT) expressed in percentage\
+| ... | of packets transmitted. NDR and PDR are discovered for different\
+| ... | Ethernet L2 frame sizes using either binary search or linear search\
+| ... | algorithms with configured starting rate and final step that determines\
+| ... | throughput measurement resolution. Test packets are generated by TG on\
+| ... | links to DUTs. TG traffic profile contains two L3 flow-groups\
+| ... | (flow-group per direction, 500k flows per flow-group) with all packets\
+| ... | containing Ethernet header, IPv4 header with IP protocol=61 and static\
+| ... | payload. MAC addresses ranges are incremented as follows:
+| ... | port01_src ca:fe:00:00:00:00 - port01_src ca:fe:00:00:c3:4f,\
